TNF and myocardial ischemia: The overall ORs demonstrated that there was no statistical association between TNF-α −238G/A gene polymorphism and IHD risk in neither genetic model (A vs G: OR = 1.10, 95% CI = 0.91–1.34, Fig. 2; (AA + GA) vs. GG: OR = 1.11, 95% CI = 0.90–1.38; AA vs (GA + GG): OR = 1.23, 95% CI = 0.69–2.21).
